The light source (110) provides a major light beam (111) and a minor light beam (112). The optical element includes a first light entering surface (121), a second light entering surface (122), a light distributing surface (123), a light emitting surface (124) and a normal line (125), wherein the normal line (125) is perpendicular to the light emitting surface (124), and the second light entering surface (122) is a scattering surface, and the major light beam (111) enters the optical element through the first light entering surface (121), and is emitted from the light emitting surface (124), and the minor light beam (112) enters the optical element through the second light entering surface (122), is reflected by the light distributing surface (123), and is emitted from the light emitting surface (124).
